Pseudomonas species are a diverse group of Gram-negative bacteria belonging to the Gammaproteobacteria class. They are rod-shaped and motile, typically possessing a single polar flagellum. Pseudomonas are ubiquitous in the environment, found in soil, water, and on plant surfaces. They are also commonly found in association with animals and humans.

Many Pseudomonas species are saprophytic, meaning they decompose organic matter, playing a crucial role in nutrient cycling. Some are plant pathogens, causing diseases in a wide range of crops. In humans, certain Pseudomonas species, most notably Pseudomonas aeruginosa, are opportunistic pathogens. P. aeruginosa can cause a variety of infections, particularly in individuals with weakened immune systems or compromised skin barriers, such as in burn victims or those with cystic fibrosis. These infections can affect the lungs, urinary tract, eyes, and skin.

Pseudomonas bacteria exhibit remarkable metabolic versatility, enabling them to thrive in diverse and often challenging environments. Their ability to utilize a wide range of substrates and tolerate various environmental conditions contributes to their widespread distribution. They are known for their production of pigments, some of which are fluorescent or colored, aiding in their identification. Research into Pseudomonas species continues to explore their ecological roles, pathogenic mechanisms, and potential applications in bioremediation and biotechnology.
